Aglaonema plant named &#39;dynamic ruby&#39;

ABSTRACT

A new and distinct cultivar of Aglaonema named ‘DYNAMIC RUBY’ characterized by its light red mottles on green ovate leaves, compact and well-branched growth habit.

BOTANICAL CLASSIFICATION

[0001] The botanical classification of the new variety is Aglaonemahybrids ‘DYNAMIC RUBY’.

BACKGROUND OF THE INVENTION

[0002] The present invention is directed to a new and distinct varietyof Aglaonema, botanically known as Aglaonema hybrids. The varietaldenomination of the new variety is ‘DYNAMIC RUBY.’

[0003] The new variety was a seedling among a progeny of Aglaonema(rotundum ‘Giant’×tenuipes)× Aglaonema brevispathum, selected by theinventor.

[0004] Asexual propagation of the new variety in Nakhon Pathom, Thailandby vegetative cuttings has demonstrated the uniformity and the stabilitythrough successive generations of this new Aglaonema.

SUMMARY OF THE INVENTION

[0005] The following traits have been repeatedly observed in the newvariety grown under shade conditions in Nakhon Pathom, Thailand whichclosely approximate those commonly used in commercial horticulturalpractice.

[0006] The features that in combination are believed to distinguish thenew variety from other known varieties of Aglaonema include: compactgrowth habit with freely branching, dense and upright growth; ovateleaves; adaxial leaf surfaces having dark green color with light redmottles.

COMPARISON WITH OTHER VARIETY

[0007] Plants of the new Aglaonema can be compared to plants of theAglaonema ‘Siam Majesty’ (U.S. Plant patent application No. 09/706,897,Filed: Nov. 6, 2000). Plants of the new Aglaonema differ from plants of‘Siam Majesty’ by the following combination of characteristics:

[0008] 1. Whereas the adaxial leaf surfaces of the new variety havelight red mottles instead of plain green as found in ‘Siam Majesty’;

[0009] 2. The mid-rib and veins of the new variety are green instead ofred as found in ‘Siam Majesty’; and

[0010] 3. The leaf tip of the new variety is attenuate while that of the‘Siam Majesty’ is acuminate.

BRIEF DESCRIPTION OF ILLUSTRATIONS

[0011] The accompanying photographs show the overall appearance of thenew variety as nearly correct as it is possible to make in a colorillustration of this type. Throughout this specification, color valuesare based upon the of The Royal Horticultural Society Colour Chartexcept where common terms of color definition are employed.

[0012]FIG. 1 shows a top view of a single plant of ‘DYNAMIC RUBY’ in a30 cm container about 15 months after planting;

[0013]FIG. 2 shows a view of the adaxial surface of a mature leaf of thenew variety; and

[0014]FIG. 3 shows the comparison between the adaxial leaf surface of‘DYNAMIC RUBY’ and its comparison variety ‘Siam Majesty’.

DESCRIPTION OF THE NEW VARIETY

[0015] All color references are in accordance with The RoyalHorticultural Society Colour Chart. Colors are approximate as colordepends on climate and environmental condition. Phenotypic expressionmay vary with environmental, cultural and climatic conditions, as wellas differences in conditions of light and soil.
